readies;

To all whom, it may concern:

Be it known that I, CARY lV. NARAMOR, a citizen of the United States,and a resident of Mecosta, in the county of Mecosta and StateofMichigan, have invented a new and Improved Sorting-Machine, of whichthe following is a full, clear, and exact description..

My invention relates generally to sorting machines and more particularlyit is directed to one particularly adapted to sort beans.

The principal'object of my invention is to provide a new and improvedmeans ofadjustably mounting disks on a rotatable shaft, the constructionbeing particularly adapted for use in bean sorting. machines.

The provision of a machine adapted to such uses which will be moreefiicient in its operation than those now in use is of someconsideration in the production of this device, along with the featureof low cost of making and operating.

Other objects and advantages of the invention will appear as thedescription thereof proceeds, the new and useful features beingparticularly pointed out inthe appended claims.

Reference is to be had to the accompany-- ing drawings forming a part ofthis specification in which similar characters of reference denotecorrespondingparts in all the views, and in which- Figure 1 is'avertical sectional view of the machine on the line 1 1 of Fig. 2; Fig. 2IS a vertical sectional view on the line 2-2 of Fig. 1.

The machine may be made in different sizes and the various elementsthereof may be differently proportioned and may be pro vided indifferentmaterials, whereby rnachines embodying the same inventive ideamaybe adapted to larger or smaller plants The machine comprises areceptacle 1 of any suitable size and formation provided with anintermediate partition 2 whereby compartments 3 and 4 result.

Rotatably supported in suitable bearings 5 is the shaft 6 preferablypositioned over the partition 2 so that one-half of, each disk carriedby the shaft lies adjacent the compartment 3, the other half of eachdisk lying adjacent the compartment 4. The shaft 6 is preferablyprovidedwith reduced ends whereby it may be supported in the bearings 5, theportions of the shaft ad acent the bearing ends being threaded as at 7,and re- Specifieation of Letters i'atent.

iceiving threaded longitudinally extending burs 8, threaded exteriorlyfor the reception cf shorter burs 9. Positioned on the shaft 6 areanumber of disks 10 10", 10, each provided with transversely extendingportions 11 11", 11, forming, in elfect, hubs, whereby the disks aresupported. Positioned on the hubs are the disks 12 1?, 12, each providedwith a central opening, the shaft 6 extending through the openings.

Between each pair of disks 10 12 10 12 and 10, 12, are the pair of disks13, 13 13, suitably secured together in any manner asby means of rivetsor pins 1%, it being noted that these disks are provided with a' numberof radially extending openings 15, whereby the peripheral portions ofthe disks may be bent in opposite directions, whereby each assumes, asit were, a dished form, these disks with the openings in them, whenpositioned between each pair of the wheel with a ll-shaped notch orgroove extending continuously around the peripheral portion thereof.

The disks 10, 10 10, are spaced from tioned hubs 11 11'", 11, while thedisks 10 and 10 are spaced from the disks 12 and 12 by the cylindricalsleeves, 16 carried on the shaft 6 and positioned between them. Theshorter burs-:9, through the medium of which the various elements areheld together in position on the shaft to rotate 1O by the cylindricalsleeve 17, and by the disk 10 to be later more specifically described.The outer ends of the long bui's 8 are enlarged as at 8*, and adapted tobe en gaged by a wrench, whereby they may be turned; the shorter burs 9are movable along these longer burs 8. In order to properly space thedisks 10, 12 10 12", 10, 12, from each other when the burs 9 aretightened and to prevent collapse of these disks under the pressureapplied by the burs, the disk 10 is provided with-transversely extendingpins 18 which pass through openings in the disk 10 and which engage thedisk 1%, this disk 12 being provided with transversely extending pins 19passing through suitable openings in the disk 10 and engaging the insideof the disk 12", this disk 12* being also provided with transverselyextending pins 20 passing through first-mentioned disks, forming, inefiect, a

the disks 12 12 152, by the before-men therewith, are spaced from thedisks 12 and suitable openings in the disk 10" and engaging the insideof the disk 12*. Thus a construction is provided whereby tightening ofthe short ,burs 9' will bring the various elements into such engagementwith the sleeves carried by the shaft and the pins carried by thedifierent disks that these disks are held secure yet are not deformed.

Referring particularly to Fig. 1, it will be noted that the adjacentinclining sides of the pairs of disks 13 13*, and 13, are provided witha'suitable flexible covering 21, which is preferably rubber, theparticular purpose ofwhich will be laterset forth. These coverings areheldin position by any suitable means, such as flanges 100, which extendaround the peripheral portions of the disks and'are suit-ably bent to beheld in place. v

-Mounted in position adjacent the disks and suitably elevated'withrespect thereto is a hopper 22 having a shaft 23 extendinglongitudinally thereof on which is a cylinder 24. provided with ainumberof openings 25, the end of the shaft'23 being provided with a pulley 26whereby the cylinder may be turned. This cylinder is so positionedwithin the hopper 22,which is adapted'to receive a quantity of beans 27which are to be sorted, that, as the cylinder turns, the openings orpockets 25 in the cylinder engage some of the beans, each pocketcarrying along a bean with it as it turns over center,- each row ofpockets 25 being adjacent a chute or outlet 28 which extends downwardlyinto position between the inclined sides of the pairs of disks 13 or13*,

or 13, which are covered with the before mentioned resilient material.

Of course, while the number of disks 011 .the shaft 6 may be varied, itis clear that the number of rows of pockets 25 on the cylinder. 2 1 willbe such" that the rows of the disks, suit-able pulleys 29 may be availedof, being suitably secured to either end or both ends of the shaft.

Cooperating with the wheels'formed by each pair of disks is a pressuredevice made up essentially of a wheel 30, the edge portions of each sideof which are preferably beveled as at 31', the wheel being adapted to beentered between each pair of resilient surfaces 21 (as shown in Fig. 1,there will be three such surfaces) a suitable mountmg or standard 32being also provlded. The

Wheel 30 is pivotally supported on apin nos-area vice 38, such as a nutor pin, there being a helical spring 39 surrounding the lever, the endsof which engage the standard 32 and the pin ornut 38. Thus the tensionof the spring keeps the wheel firmly, yet resiliently, engaged with thedisks during the rotation of the shaft 6.

A fixed'fork 40, carried on any suitable support t-l, extends betweenthe inclined resilient sides of the pairs of disks 13 and the disks 13,and the'disks 13, the purpose -of which is to engage beans held betweenthe resilient surfaces and bring them out of engagement therewith,permitting them to drop into the receptacle below the fork.

The operation of the device is as follows :The shaft 6 is rotated as isthe shaft 23, the disks then turning, as well as the cylinder 24 withthe pockets therein. The beans 27 areemptied indiscriminately into thehopper 22, the continued rotation of the cylinder 24 carrying beanssuccessively to the chute or outlet 28 by means of the pockets in thecylinder, the beans then falling down between the resilient surfaces21-carried by the pairs of disks 13 13", 13", being later engaged orbrought intoiclose engagement with such resilient surfaces by means ofthe pressure wheel 30. Any beans that are sound and firm will passaround as the shaft 6 continues to rotate, dropping into the c'om-'partment 4 of the receptacle 1; any beans that are soft oi stained willbecarried on around past the pressurewheel by the resilient surfaces 21until they are engaged by the fork {i0 and brought out of positionbetween the resilient surfaces where they drop into the compartment 3.The operation of the machine will be continuous, it requiring noexceptional care or attention,the beans which are good being separatedfrom those which are bad and being collected in separate COR l.-partments. This machine may beused with different kinds of beans ordiiferent sized beans, the device being especially adapted to a largecapacity in a small space of time, and removing a large percentage ofpoor beans with a smail percentage of good beans among them.
